PRINTING-DIE.

Specification of Letters Patent.

Patented Feb. a, rat.

a lication filed March 110, 1917. Serial in. 153,862.

To all whom it may concern:

Be it known that I, HERMAN C. Wnnrnn, a citizen of the United States,residing at Rochester, in the county of Monroe and State of New York,have invented a new and Improved Printing-Die, of which the following isa specification.

My invention, while relating to check protecting devices in general, hasmore especial reference to check writers and is an improvement over theinvention for which Letters Patent No. 1.174.642 was granted to me underdate of March 7, 1916.

In machines of this class there have been provided various ways ofhaving the cooperating printing members npt only print certain selectedwords or chhr 'acters 'on a check. or other negotiable instrument, butin so doing to break the paper throughout the printed surface in amanner that ink from the type will be absorbed by the disrupted fibers,the purpose of such mutilation being to prevent erasure for fraudulentlyraising the amount made payable.

I-Ieretofore, the construction and operation of the printing mechanismhas usually been such that ink is applied to the face only of the check.It is the object of this invention, however, to provide aplaten or diemember which, when in operative engagement with the type, efl'ects botha disruption of the fibers throughout the printed surface and an inkingof the impressed characters on both the face and reverse sides of thecheck; and a further object is to form the platen in a manner that itcan not cause injury to 'the type characters, especially their cuttingedges.

Another object of the invention is to make use of a sub-inking pad suported by the die member so that ink Wlll be supplied thereto from thetype characters when breaking through the paper during the printingoperation.

In the accomplishment of my invention, I make use of a channeled bar forreceiving a sub-inking ad and this channel is covered by a grld formedby a plurality of equally spaced parallel wires rigidly secured to thebar by a common retaining member. The type characters are carried on asupport movable relatively toward and from the die and are grooved inthe usual way to form parallel ridges which eng fe through the openingsbetween the Wires of the grid, the channeled bar being adjustablysupported so that thcre'will be proper registration of the wires withthe alternating ridges and grooves of the type.

The sub-inking pad engages the under slde of the grid and the portionsof the impressed characters forced between the wires contact with-thepad and cause the paper to be inked on the under and embossed side whllethe impressions made on the face side are inked from the type. Ink issupplied to the type by any suitable means which, when the supporttherefor comprises a type cylinder, is usually one or more ink rollersremovably held in yielding contact therewith. The pad is suitably inkedbefore being inserted to place but cannot become dry as suflicient inkto keep it in proper condition is supplied from the ridges of the typecharacters which contact therewith when cutting through the paper of theinstrument being printed.

The invention will first be described and will then be particularlydefined in the appended claims.

The accompanying drawings illustrating my invention are as followsFigure 1 is a side elevation of a check writing machine in which theinvention is adapted to be used; Fig 2, is a fragmentary portion of thetype support showing in plan view part of a line of type characters;Figs. 3 and 4, the appearance of the face and reverse sides,respectively, of a check when printed; Fig. 5, a plan view of the diemember and portion of the machine base in which it is supported; Fig. 6,a longitudinal sectional view taken along the line 6-6 of Fig. 5; Fig.7, a transverse sectional view taken along the line 77 of Fig. 5; Fig.8, a longitudinal sectional view of a portion of the die with typecharacters in engagement therewith; and Fig. 9, a fragmentary portion inside view of the channeled bar showing the grooves for receiving thegrid forming wires. Figs. 2 to 7, inclusive, are drawn to a scaleapproximately three times the actual size of the parts shown and Figs. 8and 9 to a still larger scale.

Similar reference characters refer to similar parts throughout theseveral views.

Referring first to Fig. 1.

The numeral 1 represents the base and a v the head of a check writingmachine of the character for which the invention is more especiallyintended, the front portion of the head being spaced apart from the baseto receive a check 3 therebetween which is supported on the base coverplate 4. In this machine the type bars 5 extend longitudinally of andare .carried on the periphery of a cylinder 8 revolubly supported inbearings 9 slidable in vertical extending guideways 10 in the side wallsof the head member 2. This cylinder may be turned to bring anypredetermined line of type directly above' the platen or die 11supported in' the member 12, forming an integral part of the base 1, andit is raised and lowered by the levers 13 and 14 on actuation of theoperating lever 15. At 16 are seen the usual ink rollers mounted insuitable supporting arms 17 and held in yielding engagement with thecylinder 8 for supplying ink to the characters on the several type bars.

The die member complete is referred to by the numeral 11 and comprises achanneled bar 18, sub-inking pad 19, grid 20 and retaming/member 21. Thebar 18 in length and wldth is slightly greater than the correspondingdimensions of the type bars 5, and has its upper face cut away to formside walls 22 with a longitudinally extending channel therebetween.These side Walls are slotted transversely at 23 (Fig. 9) to receive andprevent lateral movement of -the equally spaced parallel wires whichextend across the channel and form the grid 20. The ends of the wiresare turned down against the outer faces of the side walls 22 and-areheld to place by a common retaining member comprising the plate 21having an opening adapting it to engage thereover. This plate is seatedon shoulders formed at the ends of the bar 18 and is held againstremoval by ears 24 bent outwardly from the ends of the side walls 22.The ink pad 19 is contained within the channel formed in the bar 18 andis substantially the same in thickness as the depth of the channel so asto engage the under face of the grid 20.

The die 11 is supported by the base member 12 in a longitudinallyextending channel 26 and any preferred means for adjusting the die bothlongitudinally and vertically may be provided as, for instance, thatshown in the drawings wherein 25 is a screw threaded into one end of thebar 18, such screw having a shoulder 27 engaging in a transverse slot 28in the support 12, whereby turning the screw causes a longitudinalmovement of the die; and a vertical adjustment is provided for by thescrews 29 ex tending upwardly through the support 12 and engaging thebottom of the bar 18,

-While the die is normally held against displacement by the centrallydisposed screw 30 extending vertically through an enlarged opening 31 inthe support 12 and threaded into the bar 18.

The impressin members are type characters made, pre erably, of hardmetal with the face thereof serrated, as'will hereinafter be described,or of a comparatively soft composition into which the impressions of thewires forming the grid will be made by contact therewith undersuflicient pressure, the function of the type being to both print on theface of the paper and to force portions thereof through the openings inthe grid and into contact with the ink pad there- \under, the resultbein the inking of the impressed characters on 0th sides of the paper.

The type characters 32 shown in the drawings'are formed on bars 5extending longitudinally of the cylinder 8 and cast integrally on itsperiphery. Parallel grooves are formed in the type of a depth less that.the thickness of the bars above the surface of the cylinder and soangularly disposed as to register with the wires forming the grid. Thusit will be seen that the type characters have ridges alternating withthe grooves and it is preferable that these ridges be formed with sharpcutting edges.

In machines where the type characters and the platen or die havecorrespondingly formed ridges and grooves, the ridges of one or theother are often broken and their cutting edges dulled if one of suchmembers gets slightly out of alinement; but with a die made inaccordance with my invention the ridges of the type characters engage inthe open and bottomless spaces between the wires of the grid and cannotbecome injured nor their edges dulled other than by contact with thematerial of the instruments printed.

When employing my invention, the cooperation of the type and sub-inkingdie will be such as to impress the characters in the paper in a mannerto break the fibers, and, also, to ink the characters on both the faceand reverse sides of the paper, as shown in Figs. 3 and 4, respectively.The pad will be suitably inked before inserted to place but will not atany time become dry as suliicient ink will be supplied thereto from theedges of the type characters on cutting or breaking through the paperduring the printing operation.
